2 Claims.

This invention relates to multiple service hair driers or the like, andprovides improvements therein.

This invention provides improved apparatus of the kind in which air issupplied to a plurality of hoods, or other devices for delivering air,from a plurality of feeder ducts.

By the present invention means are provided for regulating the flow fromthe several feeder 1O ducts to each of the individual hoods or deliverydevices. The invention provides means whereby one or more of the hoodsmay be cut off from the feeder ducts irrespective of the location of thehoods, and it also provides means whereby the temperature of the airflowing to any one or more of the hoods may be regulated independentlyof the temperature of the air flowing to any one or more of the otherhoods.

The invention provides a novel combination D0 of the parts of a multipleservice hair drier, by which the supply of air to each of the hoods isindependently regulated by means which are simple and economical, andwell adapted for the flexibility of the operation required.

Two embodiments of the invention are illustrated in the accompanyingdrawing wherein: Fig. 1 is a view partly in longitudinal elevation andpartly in longitudinal section, of a multiple service drier providedwith a central blower. Fig. 2 is a transverse vertical section on theline 22, Fig. 1.

Fig. 3 is a horizontal sectional View on the line 3-3, Fig. 2.

Fig. 4 is a transverse sectional view similar to Fig. 2, showing asecond embodiment of the regulating means.

Referring to said drawing, A designates one feeder duct and B anotherfeeder duct. These feeder ducts may be in communication with a supply ofair of any suitable kind as for example a central blower C. In thearrangement illustrated the central blower C is constructed and arrangedto supply heated air to the feeder duct A, and air at room temperatureor thereabouts (referred to hereinafter for brevity as cold air) to theduct B. The central blower as shown comprises a housing D divided by apartition E, the space on one side of the partition communicating withthe duct A and that on the other side com- 59 municating with the ductB. A heater F of any suitable description may be placed in the housingon one side of the partition F. The heat supplied to the air on eachside of the partition F may be arranged as desired, the meansillustrated be- 55 ing in one arrangement. A fan or fans G serves toproduce a flow of air in the feeder ducts A and B.

H, H etc. designate a plurality of hoods each of which is used incommunication with an individual head on which the hair is to be dried.5 The hoods may be of conventional construction, and any other suitabletype of device for delivering air onto a head or other part of the bodymay be used.

J designates an air mixing device or chamber. 10 One of these chambersis provided for each hood, and is connected with each of the hoods insuitable manner, as by means of tubes L, which tubes may be made oftelescoping parts, to provide for height adjustments. 5

M designates means for regulating the flow from each of the feeder ductsA and B to the mixing chambers J.

Referring to Figs. 2 and 3 the common walls 0 between the feeder ducts Aand B and the chambers J are provided with openings P P Within eachchamber J is a slide R shown in these figures as a disc pivoted asindicated at R and having openings R R therein arranged in certainpositions of the pivoted slide R to register with the openings P PSuitable means for turning the pivoted slide R, are provided. As shownthese means comprise a cord Q running around the periphery of the disc Rand having ends Q Q which extend through small openings in the chamber Jand hang down in reach of the user or attendant.

The openings P P R R may be arranged in such a manner as to close offentirely the two feeder ducts from the chamber J; to open the chamber Jto one or the other feeder ducts A, B; to simultaneously open the feederducts, to increasing degrees, to the chamber J; and to increase theamount of opening to one feeder duct while the other feeder remainsfully open to the chamber J. As here shown the opening R is made longerin its; direction of travel than the' opening R By turning the pivotedslide R in a clockwise direction from the position shown in Fig. 3 theopenings P and P will be simulta- 45 neously opened to increasingdegrees until both openings P and P are fully opened. By continuedturning of the pivoted slide R one of the openings, as for example theopening P will be partly closed while the other opening P remains fullyopened. By further continued turning of the pivoted slide R the openingP will be fully closed while the opening P remains fully opened.

Referring to Fig. 4, the inner wall S of the chamber J has asemi-cylindrical shape. The

space within the cylindrical wall S is open to: the feeder ducts A and Brespectively through the openings P P The space Within the cylindricalwall S is divided by a partition S between the openings P P Thecylindrical wall is pro vided with openings T T on each side of thepartition S into the chamber J. R designates the slide for controllingthe passage through the openings T T the slide having a contourcorresponding to the contour of the semi-cylindrical Wall S and ismovable in a similarly shaped groove U. The slide R is provided withopenings R R which function similarly to the openings R R as heretoforedescribed. Openings T T R R may be arranged to function in the same Wayas the openings in the embodiment shown in Figs. 2 and 3, regarding thecontrolling and mixing of air from the feeder ducts A and B to and in,the chamber J. Sliding movements of the slide R may be e-fiected bymeans;

scribed.

What is claimed is:

1. A multiple-service drier, comprising a plurality of feeder-ducts forair, a plurality of chain bers outside of said feeder-ducts, openingsfrom each of said feeder ducts into said chambers,

means for controlling the openings from the feeder ducts into eachchamber, a tube leading from each chamber, and an air-delivery hood oneach'tube, said chambers having a greater cross-sectional area than thetubes and receiving the air, after passing said controlling means,

flowing from said openings before it passes into said tubes, said meansfor controlling the flow through said openings comprising a slidepositioned across the axis of said tube and having portions for closingboth of said duct-openings at one time and having openings thereinarranged to uncover both of said duct-openings at one time, one of saidslide-openings being longer in the direction of its movement than theother opening therein so that one duct-opening may remain fully openWhile the area of the other duct-opening is being varied.

2. A multiple-service drier, comprising a plurality of feeder-ducts forair, a plurality of chambers outside of said feedenducts, openings fromeach of said feeder ducts into said chambers, means for controlling theopenings from the: feeder ducts into each chamber, a tube leading fromeach chamber, and an airdelivery hood on each tube, said charnizzershaving a greater cross sectional area than the tubes and receiving theair, after passing said controlling means, flowing from said openingsbefore it passes into-said tubes, said means for controlling the flowthrough said openings comprising a. slide positioned across. the axis ofsaid tube and having portions for closing both of said duct-openings atone time and having openings therein arranged to uncover both of saidcluctopenings one time, said chamber comprising a semi-circular innerwall having duct-openings therein, a partition sep arating the spaceWithin said semi-circuiar inner Wall on each side of said ductmpenings,and said slide having a curvature corresponding to said semi-circularinner Wall.
